TIAAC Computer Controlled Water-to-Air Heat Exchanger Unit

The Computer Controlled Water-to-Air Heat Exchanger Unit, "TIAAC", includes a stainless steel duct with a heat exchanger in its center and a centrifugal fan at one end. The fan impels the air through the heat exchanger.

The heat exchanger consists of a finned radiator through which a hot water flow coming from a tank circulates. This radiator is placed perpendicular to an air flow generated by the fan (computer controlled).

Hot water flows through a closed circuit. A heating element (computer controlled) immersed in the stainless steel tank heats water to a specific temperature. Water leaves the tank and is impelled by a pump (computer controlled). Part of the water enters the exchanger and part returns to the tank by a bypass. The bypass has a valve to regulate the flow of hot water. Water passes through a flow sensor at the exchanger’s inlet.

The hot water circuit has two ball valves to control and drain hot water at the exchanger.

There is a series of temperature sensors that allow to measure the temperature at the inlet and outlet of the exchanger of both the hot water and air, and the water temperature in the tank. There is a water flow sensor and an air flow sensor to measure the hot and cold flow.

The tank includes a level switch to guarantee a specific level inside the tank and there is a pressure sensor after the pump that allows to study the characteristic curve of the pump.

This Computer Controlled Unit is supplied with the EDIBON Computer Control System (SCADA), and includes: The unit itself + a Control Interface Box + a Data Acquisition Board + Computer Control, Data Acquisition and Data Management Software Packages, for controlling the process and all parameters involved in the process.
